Salt water pool conversion.

The Hayward/Goldline system is tried and true. The Jandy is actually a Zodiac unit (they own Jandy) and Zodiac does not make the best SWCGs IMHO. The Jandy unit operates at a higher salt level (about 4000 ppm) than the Hayward (3200 ppm) and produces less chlorine. The Jandy produces .97 lbs a day (and is a closer match to the Hayward system with a T9 cell, rated for 25000 gallons)) while the Hayward with the T15 cell produces 1.47 lbs a day and has a longer warranty on the cell. Mine is still going strong 7 years later (however it is also very oversized for my pool!)
In my experience Jandy/Zodiac tend to push the limit on how many gallons their units can handle.

FWIW, the Hayward is also auto reverse polarity (auto cleaning). No matter what unit you get be sure to run the CYA at the MAXIMIM recommeneded level and keep the FC at 5% of that and you should not have any problems. Since for the Hayward unit this is 80 ppm you would run the FC at 4-5 ppm while for the Jandy unit it is 50 ppm so you would run the FC at 3 ppm (which is not a good idea in a climate with high UV index, nor is CYA at 50 ppm).

IMHO, go with the Hayward with a T15 cell.

I've got the Hayward unit and I'm pretty happy with it. I'm going on 18 months here, cell was in place when I bought the house so I'm not really sure how old it is.

Cell cleaning really isn't a big deal, as pooldoc said, 5 minutes (or less) to take it out and inspect.

BTW, the Hayward T15 cell is the one you are looking at. It is the 40K gallon rated one. The T9 is rated at 25k gallons and is a closer match in chlorine production to the Jandy unit.

Also, my Hayward/Goldline runs year 'round since I am located in Florida and also have a high UV index.
